Add CH592 to Readme

[plops]

I used managed to program a board with CH592F using wchisp.
I bought it from here: aliexpress.us/item/1005006117859297.html

cl-cpp-generator2/example/146_mch_mcu/source06/b $ ./wchisp flash risc_usb_test

19:48:50 [INFO] Device reset

I have to press the BOOT button while plugging in the USB-C cable.
Only then the USB device enumerates in Linux and wchisp can program.
I believe if I don't program the device immediatly, then after 10 seconds I have
to press BOOT again and plug USB again.

My code for the target is here: https://github.com/plops/cl-cpp-generator2/tree/master/example/146_mch_mcu/source06
